Shared groceries and household items: what to split and what to keep separate

What to split and what to keep separate, and three ways to handle shared household buys.

Two housemates unpacking grocery bags in a small kitchen.

Dish soap, toilet paper, rice, cooking oil. Shared households go through them fast, and someone always seems to buy them more often.

Draw a clear line

Most housemates do well with two lists.

Shared: cleaning products, toilet paper, bin bags, cooking basics such as rice, oil, salt and sauces, and anything everyone uses.

Personal: your own food, snacks, drinks and toiletries.

Write the lists down and stick them on the fridge, or keep them in a shared note.

Three ways to handle shared buys

  1. Take turns. Each person buys the shared items in turn. Easy, but it only works if costs are similar each time.
  2. Keep a running tab. Whoever buys records the amount. Settle the balance every month.
  3. Shared kitty. Everyone puts in a fixed amount each month, such as S$30, and shared items are paid from it.

The running tab is the fairest when people shop at different times.

A worked example

In one month, three housemates record their shared buys: Lina S$64, Omar S$22, Wei S$34. That is S$120 in total, or S$40 each. Omar pays Lina S$18 and Wei pays Lina S$6, and the month is square.

Cooking together

If you cook together often, split the groceries for those meals equally and keep everything else personal. It keeps the shopping trip simple.

Small amounts add up

Do not skip recording a S$4 bottle of dish soap. Small amounts are the ones that build quiet resentment over a year.
